command line application in node for searching key value in json .log file

Question

I am using only yargs and not GREP for this and trying to implement simple commands as -v to return an object in which the value match or -k to return an object in which the key match and I am returning this in the terminal itself using the console.log.

So, the problem is that the data is in even JSON .log file and I can't just parse it so I was converting it into an array first and then using it for the actual searching. Is there a way for searching an uneven array for key/value if found then return that JSON object using Yargs?

The JSON .log file type

{"request": "/forumData", "verb": "GET", "host": "codesnip.com", "request_id": "dc9be12fca2e9065799109ca97cb14a7", "port": 8088, "app": "iOS:2.22.14", "event": "res-json", "time": 0.946825095, "level": "info", "message": "", "timestamp": "Thu Oct "}

and I am converting it into an array by

const read = new Promise((resolve, reject) => {
    fs.readFile('json_sample.log', (err,data) => {
        var temp = JSON.parse(JSON.stringify(data.toString()))
        while(temp.trim().length > 0){
         var trim = temp.substring(temp.indexOf("{"), temp.indexOf("}") + 1)
          temp = temp.replace(trim, "")
          arr.push(JSON.parse(trim))
        }
        console.log(arr)
        resolve(arr)
    })
})

read.then((e) => console.log(e))
